I am running -current on my T420 at r263906M debug.acpi.acpi_ca_version: 20130823 o/p of sysctl -a | grep acpi - http://bpaste.net/show/199806/ and I have following in my rc.conf: performance_cx_lowest="Cmax" economy_cx_lowest="Cmax" But I still get: % sysctl -a | grep cx_lowest hw.acpi.cpu.cx_lowest: C1 dev.cpu.0.cx_lowest: C1 dev.cpu.1.cx_lowest: C1 dev.cpu.2.cx_lowest: C1 dev.cpu.3.cx_lowest: C1 And I can do: # sysctl dev.cpu.0.cx_lowest=Cmax dev.cpu.0.cx_lowest: C1 -> C8 that tells me that Cmax is C8. % sysctl -d dev.cpu.0.cx_lowest dev.cpu.0.cx_lowest: lowest Cx sleep state to use I was expecting cx_lowest to be set to C8 because of rc.conf config I have. What am I missing here? cheers, Hiren
